Ladies, if you’re about to give birth, or you’ve just had a baby and you think your guy is getting more irritable every day, it may not be your imagination.

Ten percent of fathers get prenatal or postpartum depression, according to a new study. Unlike women with the same condition, who tend to become sad and withdrawn, men tend to be angry and grouchy.

The study, done by researchers at Eastern Virginia Medical School, shows that dads’ depression peaks when the baby is three to six months old, according to Yahoo! News. Responses covering that time period indicated that 25.6 percent of fathers are depressed.

And postpartum depression for both genders was most severe in the United States, researchers said. American moms and dads are more stressed than parents in Europe, Australia, South America and China.

"Three months is when family leave runs out [in the United States], and I can't help but wonder if that has something to do with it," said lead researcher James Paulson. "But there is also a lot going on with the child by that time." At that stage of growth, infants can be more demanding; for example, they might want to be held all the time.

Paulson said that the depression of one or both parents can have an effect on the entire family, and that mothers and fathers should be “on the lookout for it”. (Yahoo! News)
